Two Statistics Problems

Table 8-35 gives the stopping distance d(feet) of an automobile traveling at speed v (miles per fou) at the instant danger is sighted. (a) Graph d against v. (b) Fit a least-squares parabola of the form d = a + bv + cv^2 to the data. (c) Estimate d when v = 45 miles per hour and 80 miles per hour. (See attachment for table and other question)
